New features have been brought to the action puzzler title, PUK, including two new difficulty modes: Shadow and Light. These new modes have unique graphics and soundtracks for players to enjoy. Shadow has been designed to challenge the hardcore players, while Light gives the new guys a chance to learn how things work.

Shadow mode holds the biggest challenge seen in PUK thanks to having little time to aim and a nasty speed curve. Light mode holds the rookies hand as it features easier levels and more time to get a feel for the game.
